On their view this broad freedom is exercised even toward the last end, and natural necessity does not lessen it
This, in their view, is the freedom the will exercises in all its acts. It does so not only when dealing with the means to the end, or with things that contribute little or nothing to the end, but also when dealing with the end itself.
So the necessity that flows from the will's nature and agrees with it, by which the will is set on pursuing the highest end, in no way destroys or lessens this freedom of the will.
Latin
XXII. Haec est illa libertas, quam ex eorum sententia, voluntas in omnibus suis actionibus exercet, idque non tantum quum versatur circa media ad finem spectantia, aut ea quae parum, aut nihil ad finem conducunt, sed etiam, quum versatur circa ipsum finem. Ac proinde ipsa necessitas quae voluntatis naturam sequitur, eique consentanea est, & per quam determinata est ad summum finem prosequendum, hanc voluntatis libertatem minime evertit, aut minuit.
